Node. js implements port forwarding and node. js port forwarding

This article shares the node. js port forwarding implementation code for your reference. The specific content is as follows:

#!/sbin/node var net = require('net'); function proxyPort(srcport,destServer,destport){  var server = net.createServer(function(c) { //'connection' listener     c.on('end', function() {        console.log('src disconnected');    });     var client = net.connect({port: destport,host:destServer},function() { //'connect' listener         console.log('ok....');         c.on('data', function(data) {             console.log(data.length);           client.write(data);         });    });     client.on('error', function(err) {     console.log("dest=" + err);     c.destroy();    });     c.on('error', function(err) {     console.log("src" + err);     client.destroy();    });     client.on('data', function(data) {     c.write(data);    });     client.on('end', function() {     console.log('dest disconnected ');    });   });  server.listen(srcport, function() { //'listening' listener   console.log('server bound' + srcport);  });} var params = process.argv;if(params.length != 5){ console.log("node port.js srcport destserver destport ");  return;} proxyPort(params[2],params[3],params[4]); console.log(process.argv);
